BUILD Libri GmbH Build Smart Devices with Esp32

Want to move beyond simply following code and actually understand how smart devices are built? BUILD SMART DEVICES WITH ESP32 gives beginners a practical path from their first ESP32 setup to building, connecting, troubleshooting, and designing their own connected devices.

You will learn how the ESP32 works, how to program it with Arduino IDE, and how hardware and software interact. Step by step, you will work with GPIO, sensors, PWM, ADC, I²C, SPI, UART, Wi-Fi, Bluetooth, and practical IoT concepts without being buried in unnecessary theory.

The book is built around real projects that progressively increase in capability. You will build interactive LED and button controls, an adjustable LED dimmer, motion-activated lighting, distance alerts, environmental monitors, display systems, Wi-Fi devices, remote controllers, and practical home automation systems. A complete capstone project brings these skills together.

What makes this guide different is its emphasis on understanding, not copying. Each stage helps you learn why the hardware and code work, modify existing projects, diagnose failures, and develop a repeatable build-test-debug workflow.

You will also learn how to troubleshoot wiring, power, programming, libraries, uploads, Wi-Fi, Bluetooth, and IoT connectivity, giving you practical skills that remain useful beyond the projects in this book.

Whether you are exploring electronics, learning programming, or beginning your IoT journey, this book gives you a structured path from first build to independent smart-device development.
